Fruit flies which were heterozygous for both autosomal dominant traits aristapedia (Ar) and
star eyes (S) were mated. Since aristapedia and star eyes are both lethal when homozygous
and unlinked, one would predict ratio of 4:2:2:1 for Ar-S to Ar to S to wild type (+). Among
the offspring flies, there were 113 Ar-S, 55 Ar, 73 S, and 38 +. Test the hypothesis of a
4:2:2:1 phenotypic ratio at the 5% level of significance.
